public interface GenericDao<T,ID extends java.io.Serializable>

A generic data access object (DAO) based on the GenericDAO class found in the Hibernate distribution.

All CRUD (create, read, update, delete) basic data access operations are isolated in this interface and shared accross all DAO implementations. The current design is for a state-management oriented persistence layer (for example, there is no UDPATE statement function) that provides automatic transactional dirty checking of business objects in persistent state.
